4.1.4 Accessories and consumables
In order to ensure reliable, high-quality results, product safety, and
durability, our range of CEREC Primemill production units must only be
operated with original accessories and consumables from Dentsply
Sirona or approved accessories and consumables from third-party
suppliers.
In particular, only the power cable also supplied or the corresponding
original spare part may be used with the unit. The user is responsible
for any damage resulting from the use of nonapproved accessories and
consumables.
Approved accessories and consumables include grinding/milling tools,
blocks and coolants. The current selection of approved blocks and
corresponding grinding/milling tools can be found in the latest software
as well as in "Bur tables for the CEREC milling and grinding units" in the
download area at:
https://my.cerec.com
These lists are updated from time to time.
4.2 Opening the processing chamber door during
the machining process
CAUTION
Coasting tools
When the processing chamber door is opened during the machining
process, it may take a short time (approximately 2-3 seconds) for the
tools to coast to a stop.
➢ Be careful not to touch the tools with your hand or any other
object during this time.
➢ Avoid opening the processing chamber door while the production
unit is in operation.
➢ Before you open the processing chamber door, end any actions
that are running by pressing the "Stop" button on the touch
interface of the production unit or in the application software.
4.3 Electrostatic charge
4.3.1 ESD warning labels
ESD warning label CAUTION
Risk of injury or damage to components from electrostatic discharge
For electrical components labeled with an ESD warning label,
observe the following instructions.
➢ Apply the ESD protective measures.
➢ Do not touch connector pins or sockets without applying ESD
protective measures first.
➢ Do not establish any connections between these connectors
without applying ESD protective measures first.

D3692.201.01.01.0201.2020
4.3.2 ESD protective measures
ESD ESD stands for ElectroStatic Discharge.
ESD protective measures ESD protective measures include:
● Procedures for preventing electrostatic charge build-up (e.g. air
conditioning, air moistening, conductive floor coverings and non-
synthetic clothing)
● Discharging the electrostatic charges of your own body on the frame
of the UNIT, the protective ground wire or large metallic objects
● Connecting yourself to ground using a wrist band.
Training We therefore recommend that all persons working with this system be
instructed on the significance of this warning label. Furthermore, they
also should receive training in the physics of electrostatic discharges
which can occur in the practice and the destruction of electronic
components which may result if such components are touched by
electrostatically charged USERS.
The content of this training is explained in the Chapter "About the
physics of electrostatic charges" [→14].
4.3.3 About the physics of electrostatic charges
What is an electrostatic charge? An electrostatic charge is a voltage field on and in an object (e.g. a
human body) which is protected against conductance to ground
potential by a nonconductive layer (e.g. a shoe sole).
Formation of an electrostatic charge Electrostatic charges generally build up whenever two bodies are
rubbed against each other, e.g. when walking (shoe soles against the
floor) or driving a vehicle (tires against the street pavement).
Amount of charge The amount of charge depends on several factors:
Thus the charge is higher in an environment with low air humidity than
in one with high air humidity; it is also higher with synthetic materials
than with natural materials (clothing, floor coverings).
Electrostatic discharge must be preceded by electrostatic charging.
The following rule of thumb can be applied to assess the transient
voltages resulting from an electrostatic discharge.
An electrostatic discharge is:
● perceptible at 3,000 V or higher
● audible at 5,000 V or higher (cracking, crackling)
● visible at 10,000 V or higher (arc-over)
The transient currents resulting from these discharges have a
magnitude of 10 amperes. They are not hazardous for humans because
they last for only several nanoseconds.

4.4 Wireless phone interference with equipment
67 19 681 D3692
D3692.201.01.01.0201.2020 15
Background Integrated circuits (logical circuits and microprocessors) are used to
implement a wide variety of functions in dental/X-ray/CAD/CAM
systems.
The circuits must be miniaturized to a very high degree in order to
include as many functions as possible on these chips. This leads to
structure thicknesses as low as a few ten thousandths of a millimeter.
It is obvious that integrated circuits which are connected to plugs
leading outside of the unit via cables are sensitive to electrostatic
discharge.
Even voltages which are imperceptible to the user can cause
breakdown of the structures, thus leading to a discharge current which
melts the chip in the affected areas. Damage to individual integrated
circuits may cause malfunction or failure of the system.
To prevent this from happening, the ESD warning label next to the plug
warns of this hazard. ESD stands for ElectroStatic Discharge.
Connector pins or sockets bearing ESD warning labels must not be
touched or interconnected without ESD protective measures.
4.4 Wireless phone interference with equipment
The use of mobile wireless phones in practice or hospital environments
must be prohibited to ensure safe operation of the unit.

4.5 Disturbance of data transmission

D3692.201.01.01.0201.2020
4.5 Disturbance of data transmission
Note on wireless communication Data communication between the acquisition unit and the CEREC
Primemill production unit should preferably be wireless data
communication via WLAN.
As for all wireless connections (e.g. cell phones), heavy utilization of the
available radio channels or shielding caused by building installations
(e.g. metal-shielded X-ray enclosures) may impair the quality of the
connection. This may become noticeable through a reduction in range
and/or a slower data transmission rate. In extreme cases, it will be
impossible to establish a wireless connection at all.
Dentsply Sirona has selected the best possible configuration for data
communication via WLAN, which generally provides perfect functioning
of this connection. However, in individual cases unrestricted wireless
data communication may be impossible for the reasons mentioned
above and/or due to local circumstances. In such cases, a cable LAN
connection should be selected to ensure uninterrupted operation. If the
only LAN interface on the rear of the acquisition unit is occupied by
another plug, remove this wireless interface connection and instead
connect the LAN cable with the CEREC Primemill production unit.
4.6 Ventilation slots
Under no circumstances may the ventilation slots on the unit be
covered, since otherwise the air circulation will be obstructed. This can
cause the unit to overheat.
Do not spray liquids such as disinfectants into the ventilation slots. This
may lead to malfunctions. Use wipe disinfection only in the vicinity of the
ventilation slots.
